CONCEPT OF GERONTOLOGY AND GERIATRICS

Аннотация

This article explores the fundamental concepts of gerontology and geriatrics, highlighting their definitions, classifications, historical development, and roles in addressing the health and social challenges of aging populations. It emphasizes their importance in modern society, particularly in the context of increasing life expectancy, chronic disease management, andtheglobal push toward healthy and active aging. Keywords: gerontology, geriatrics, aging population, chronic diseases, elderly care, activeaging, health policy In the context of global population aging, the disciplines of gerontology and geriatrics have gained increasing significance in both scientific research and practical healthcare. These two closely related fields play a crucial role in understanding the biological, psychological, and social aspects of aging, and inimproving thequality oflifeof elderly individuals. Gerontology is the interdisciplinary scientific study of aging and the problems that elderly individuals face. It covers the biological, psychological, and sociological dimensions of aging and seeks to understand the processes that contribute to aging and age-related decline. Gerontology does not only focus on the elderly, but also examines the aging process across the human lifespan. Themain branches ofgerontology include:  Biogerontology–studies thebiological mechanisms of aging.  Socialgerontology –focuses onthesocial roles and changes that accompany aging.  Psychogerontology –explores thecognitiveandemotional changes that occur with age.  Environmental gerontology – studies how physical environments affect the aging process and well-being. Gerontology is often used to inform policies on elderly care, retirement, social security, urban planning, and healthcare services. Geriatrics, on the other hand, is a medical specialty focused on the health care of elderly people. It aims to promote health by preventing and treating diseases and disabilities in older adults. Geriatricians are physicians trained to diagnose, manage, and treat the complex health needs of aging patients. Key characteristics ofgeriatrics include:  Multimorbidity management: Treating multiple chronic diseases (e.g., diabetes, hypertension, arthritis) simultaneously.  Polypharmacy monitoring: Ensuring the safe use of multiple medications to avoid adverse drug reactions.  Functional assessment: Evaluating an elderly patient's ability to perform daily activities andliveindependently.  Cognitive and mental health: Addressing age-related conditions like dementia, depression, or delirium.  Palliative and end-of-life care: Ensuring quality of life in the terminal stages of chronic illness. http://www.internationaljournal.co.in/index.php/jasass 367 Volume 15Issue 05, May 2025 Impact factor: 2019: 4.679 2020: 5.015 2021: 5.436, 2022: 5.242, 2023: 6.995, 2024 7.75 The significance of gerontology and geriatrics in the modern world cannot be overstated. The global population is undergoing a profound demographic transformation characterized by a rapid increase in the number and proportion of elderly individuals. According to the World Health Organization (WHO), the global population aged 60 years and over is expected to reach 2.1 billion by 2050, up from 1 billion in 2020. This demographic trend, often referred to as “population aging,”has far-reaching implicationsfor publichealth, economics, social policy, and healthcaresystems. Here are the differences between gerontology and geriatrics inthe figure: Advances in medicine, public health, and living standards have contributed to a significant rise in life expectancy across the world. While this is a testament to global development, it also results in a growing elderly population that requires targeted health services and social support systems. Countries with aging populations – such as Japan, Germany, Italy, and increasingly China and the United States – are facing mounting pressure to reform healthcaredelivery, pension systems, and long-term care infrastructure. However, gerontology also highlights the economic opportunities of an aging society. This includes the emergence of the “silver economy” – a market sector focused on products and services tailored to older adults, such as assistive technologies, age-friendly housing, telemedicine, and elder tourism. Moreover, older individuals represent a valuable resource of experience, skills, and knowledge. Through policies that encourage active aging, societies can harness this potential via volunteerism, part-timeemployment, ormentorship programs. Recent advancements in digital health, artificial intelligence, and wearable devices offer promising tools to support elderly care. Telemedicine, for example, enables remote consultations, reducing barriers to access for elderly individuals with mobility limitations. Smart home systems can monitor daily activities, detect falls, and alert caregivers in emergencies. Gerontology researchers and geriatric practitioners are in
